Highweed..
You can cover a 4x4 area with a 1000watt HPS very very well.
A great high yielding quick grow would be to grow 16 plants about 10-14 inches tall during vegging and then flower them...


this would have the potential for a great grow!!!


Now if you dont use the 1000watt bulb properly.. you might as well have a 400watt bulb...

MOST GROWERS DO NOT KNOW HOW TO... OR DONT USE A 1000WATT BULB TO ITS FULL POTENTIAL.. EVERY 12 INCHES.. THE BULB LOOSES HAVE OF ITS LUMES....LUMENS = GROWING POWER = BUD SIZE = BUD WEIGHT..

so you need the light to be as close as possible... if somebody tells you the light should be 10 icnhes away... A great grower will cool that light down so much that he can get it 5 inches away and he will yield 2+ ounces from every plant harvesting 2+ POUNDS using only one 1000 watt bulb!!!!!

AND NOW YOU KNOWM

if you accept this very moment...you will BE LOVE
